Solving the charging problem
https://www.autoblog.com/2019/12/26/vw-charging-robots/
This is something that could solve the "not everyone has easy access to a charger" problem I've harped on. After hearing the idea, I can picture parking in a garage, lot, or on the street for the night and hailing a charging robot like an Uber to give a charge. Imagine this would be ridiculously expensive and inefficient as described and totally impractical (and reliant on self-guided robots actually learning how to use sidewalks properly (something they're not very good at yet)), but it's an entirely different approach to solving the problem that's not tied to "this is how we've always done it" model. |
Why did my mind go right to the WALL-E movie

Personally speaking, I can easily solve the charging problem:
I won’t buy a Tesla. IMO, the inconvenience of finding a charging station (especially in rural NV) outweighs the benefits of owning one. But that may change, so who knows ?? |
I'm struggling to understand what problem this helps solve. VW charging robots seem overly complicated -- I give it very limited odds of rolling out beyond a demonstration site or two.
Having driven an EV for over 6.5 years and over 100k miles, charging is not a problem. Most charging is done at home -- in my case over 80% of my charging has been at home (which is on the low side -- but only since we've taken so many road trips). Tesla's Supercharger model works very well for road trips -- and most gaps have been closed. Many hotels have added charging which lets you top up overnight -- and they are becoming easier to find (PlugShare has a good search filter). For rural charging, RV parks help fill gaps (and any equipped with a 50A outlet can be used to charge a Tesla at over 30 miles of charge per hour). Even plugging in at a regular 120V outlet can add range in an emergency (albeit slowly -- but overnight can add ~30ish miles, which should be enough to get to a faster charger)... The only charging problem is in larger cities where people park on the street and don't have access to an outlet. I don't see how VW's robot charging battery delivery really helps in this situation. Better solutions are to make chargers avail on street parking. I've seen that in multiple cities in Europe, and LA has started adding chargers to street lamps -- https://bsl.lacity.org/smartcity-ev-charging.html Another potential solution is workplace charging -- my employer has it at some sites (although not at my office due to a weird thing with our county-owned garage that used federal funds to put in dedicated spots for carpoolers, but no dedicated EV spots...). |
Yes, the real, practical solution is the one that zbb identifies--adding charging infrastructure to street lamps and other existing parking. That isn't perfect, and charging for people who don't have single family homes is always going to be less convenient, but it makes a lot more sense to me than charging robots.
The key point here is that if these Level 2 charging outlets are ubiquitous, you don't need to make them fancy and expensive Level 3 fast chargers--though you will have to have those, as well. |

The tricky part is making sure the house wiring is designed to support the load, but in new construction/rehabilitation that's easy enough to do. Same principle applies to parking, especially where you've already got electrical infrastructure. Is it an easy problem? Yes. Is it cheap? Not especially, but then again, burning fossil fuels ain't free, either. |

Can existing streetlight infrastructure handle the load of charging cars, too? Or would it be cheap and easy to upgrade? And even though you're tapping into the streetlight infrastructure, it's not like there's a streetlight for every spot on the street or in a parking lot (many garages are a different story), so you still need to add a lot of stuff to have places to put the chargers when they're not in use, etc. :dunno: Installing and maintaining millions of chargers (and method for attributing billing) that will sit idle almost all of the time seems like it would be wastefully expensive and inefficient to build out. That doesn't mean it won't turn out of the be the least expensive and most efficient way to solve the problem. Robots aren't cheap either. I'm sure there's something. I'm not sure anyone's thought of what it is yet. |
I guess this is the best thread to post a link to a great article on fast charging infrastructure published in Bloomberg yesterday...
https://www.bloomberg.com/news/featu...s-green-future Premise is that Tesla is way ahead and that while other networks are being built up, there are gaps -- and that in-car maps don't do a good job distinguishing between L2 (6-10kW charging) and L3 (50kW+ fast charging)... |
